I am using 80% of my time working with Dasung eink monitor. The advantages are:
-Zero eyestrain
-Focussed work/Less Distraction
-Less temptation to do anything else (e.g. videos) because its not inviting to do so
-More energy after work day and improve of sleep quality
-No Bluelight exposure
Disadvantages: -Only BW so need to look at normal screen for graphics -Needed two eink screens otherwise two small to work (but ordered now the 25inch one)
Here is a pic of my setup (actually Dasung featured it): https://twitter.com/DasungTech/status/1391693381726658561/ph...
The 25 inch screen is already out and ordered mine, can't wait for it to come: https://www.indiegogo.com/projects/paperlike-253-the-first-2...
